Write some Software

Mainly, it has two main phases; namely Map phase and Reduce phase. In each one of these, you have sub-phases. Briefly, on a cluster of nodes/cores, during the Map phase, the cluster nodes running the map program should emit key-value pairs based on the split chunks of the input file. These key-value pairs will be consumed by the cluster nodes running the reduce program. The reduce component usually summarizes the data received by the map phase to produce the final output after the combining the output coming from several nodes. In this project you will be solving the problem of counting the neighboring nodes of a node in a network. If two nodes have a link/an edge, they are considered neighbors. You can think of the network as Friendship network (nodes are friends and links represent friendship relations), Co-Authorship network (nodes are authors and links represent common work) …etc. You will be given a network file. The file has the network you will work with. When you download the file from the link given below, you need to open it. You can extract the compressed file using WinRAR for instance. To open the network file, notepad or notepad++ will not be a good choice because the file is huge for a simple text editor. However, you can open it using a free editor such as PilotLite. The file needs a very simple cleaning. You need to remove the first 4 lines in order to keep the network only.
